Split Lock Washers for Socket Head Screws
Also known as high-collar lock washers, these have a smaller outside diameter than standard split lock washers to fit neatly under socket head cap screws. As the screw is tightened, these washers flatten to add tension to the joint. This counteracts fatigue around the joint from small amounts of vibration, making these washers a common choice to prevent fasteners from loosening. However, compared to other locking washers, they resist the least amount of vibration.
These washers are compatible with fasteners that have right-hand threads to prevent loosening. The uneven split ends bite into fasteners for a tight grip, but they won’t work with hardened surfaces. These washers hold better than curved or wave washers. They are not reusable after tightening.
316 stainless steel washers have excellent resistance to chemicals and salt water. They may be mildly magnetic.
18-8 stainless steel washers have good chemical resistance and may be mildly magnetic. Black-oxide 18-8 stainless steel washers have a matte black finish.
Black-oxide steel washers are mildly corrosion resistant in dry environments. Zinc-plated steel washers are corrosion resistant in wet environments.
Washers that meet ASME B18.21.1 adhere to strict dimensional standards. Steel washers also meet standards for material properties.
